The Goethe impact basin hosts some of the most remarkable tectonic deformation observed on Mercury -- but this deformation is not restricted to its interior. A number of wrinkle ridges line its perimeter, examples of which we have seenbefore. In this scene, several ridges and lobate-like landforms (that are likely tectonic but resemble lava flow fronts) occur along the basin's northern margin.

This image was taken when the Sun was very close to the horizon, which serves to lengthen shadows and emphasize topographic relief. Although the basin's interior is filled with smooth plains, low-Sun images show even smooth plains to be pock-marked with small craters. Nonetheless, the lighting in this scene clearly illustrates the difference in texture between Goethe's (relatively) smooth plains infill and the much more rugged intercrater plains that surround the basin.

This image was acquired as part of MDIS's campaign to image within regions of permanent shadow in ice-bearing polar craters. Imaging with the WAC broadband clear filter, which has a bandwidth of 600 nanometers and is used for calibration imaging of stars, has the potential to reveal details of shadowed surfaces that are weakly illuminated by scattered sunlight. NAC images obtained with long exposure times are also acquired to seek details within shadowed regions. A variety of image exposure times and viewing conditions are employed to maximize the opportunity to resolve surface features of areas in permanent shadow.

The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet. MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
